1. What is the definition of hydraulics?
Hydraulics is basically the liquid version of pneumatics. In fluid power, hydraulics is used for the generation, control & transmission of power by the use of pressurized liquids. This covers concepts such as pipe flow, dam design, fluidics, and fluid control circuitry, pumps, turbines, hydropower, computational fluid dynamics, flow measurement, river channel behavior, and erosion.
2. What is the definition of pneumatics?
Pneumatics is the use of pressurized gases to produce mechanical motions. Pneumatic systems are used in industry & factories extensively.
3. Name 4 hydraulic devices:
Backhoes, bulldozers, car crushers & jaws of life are 4 hydraulic devices.
4. Name 4 pneumatic devices:
Air compressors, paint-spray equipment, sanders and buffers are 4 pneumatic devices.
5. How do hydraulic systems work?
The hydraulic system is quite simple. Force that is applied to one point is transmitted to another point using an incompressible fluid. The force is almost always multiplied in the process. The brakes in your car are a good example of a piston-driven hydraulic system.
6. How do pneumatic systems work?
Pneumatic systems are similar to hydraulic systems, with the same idea. But hydraulic systems use incompressible fluid, while pneumatic systems use compressible air. Filtered air is pulled through system by a vacuum pump. Evacuated air passes through the instrument case which causes gyro to spin. Spinning gyros provide 'rigidity in space' for instrument references. Air exhausts through the Gyro pressure gauge exhaust port.
7.What are the major differences between hydraulic and pneumatic systems?
Hydraulic systems use incompressible fluid, while pneumatic systems use compressible air.
